The Mac Pro is a very fast and capable OS X machine, but it's an even faster Windows Vista machine. Vista really flies on this beast, and feels like it's faster than OS X - it boots faster, folders burst open and apps launch instantly.... I'm especially delighted with Vista's "glass" Aero interface, which works in all its glory on this machine.

The Mac Pro's a meaty piece of hardware and BootCamp makes you restart to switch to Windows. Can't wait to see Vista on a Macbook Pro with Parallels. — Gina Trapani
